In Spiritual Criminals, Michelle M. Nickerson shares a complex portrait of the Camden 28, a passionate group of grassroots religious progressives who resisted both their church and their government as they crusaded against the Vietnam War. Priests, nuns, and devout lay Catholics, the members of this coalition accepted the risks of felony convictions as the cost of challenging the nation's military-industrial complex and exposing the illegal counterintelligence operations of the FBI. By sharing layers of political history, theological traditions, and the Camden 28's personal stories, Nickerson reveals an often-unseen spiritual side of the antiwar movement. At the same time, she probes the fractures within the group, detailing important conflicts over ideology, race, sex, and gender that resonate in the church and on the political Left today.
